Abstract
The invention relates to a method and an apparatus (1) for the timing of signals (2), preferably of signals (2) including fast changing disturbances, the apparatus (1) comprising a first timer (3) and a second timer (4), the first timer (3) is characterised by a first decay time (5) and first attack time (5) and the second timer (4) is characterised by a second decay time (6) and second attack time (6), the second attack time and the second decay time are faster than the first attack time and the first decay time and wherein an input signal (2) will be treated in parallel by the first timer (3) and second timer (4).
Claims8
An apparatus for timing a signal, comprising:
- a first timer;
- and
- a second timer,
- wherein the first timer has a first decay time and a first attack time and the second timer has a second decay time and a second attack time,
- the second attack time and the second decay time are faster than the first attack time and the first decay time, respectively,
- wherein during operation said signal is timed in parallel by the first timer and the second timer, and
- wherein during operation an output signal of the first timer is subtracted from an output signal of the second timer to generate a difference signal.
A method for timing a signal, comprising:
- providing an apparatus having a first timer and a second timer, wherein the first timer has a first decay time and a first attack time and the second timer has a second decay time and a second attack time, and the second attack time and the second decay time are faster than the first attack time and the first decay time, respectively,
- timing said signal in parallel using the first timer and the second timer, and
- subtracting an output signal of the first timer from an output signal of the second timer to generate a difference signal.
